Description
Technical field
The present invention relates to a kind of pitch and its preparation and application, and in particular to a kind of nano modification emulsified asphalt and its
Preparation and application.
Background technology
Domestic ＆ Overseas Asphalt Pavement regeneration techniques are divided into four major class at present, are hot in-plant reclaimed, on-site heat regeneration, plantmix respectively
Cold renewal, on-the-spot cold regeneration.What application was most at present is plant-mix heat recycle technology, technology relative maturity, the stable quality, but energy
Consume it is excessive, new pitch, it is new gather materials very high temperature is required heat in mixing process with waste and old RAP, environment can be caused dirty
Dye, can not accomplish maximizing the benefits, so cold recycling technology (emulsified asphalt cold renewal and foamed asphalt cold renewal) has centainly
Advantage, can not only realize recycling for waste and old RAP, moreover it is possible to accomplish room temperature construct, ensure reclaimed bituminous pavement usability
While energy, environmental pollution will not be also caused；Especially emulsified asphalt cold recycling technology, in the maintenance of China's asphalt pavement maintenance
It is used widely.
Emulsified asphalt cold recycling technology refers to the waste and old RAP progress crushing and screenings by recycling in the special equipment of use, and
With it is a certain proportion of newly gather materials, regenerate stabilizer, active filler, emulsified asphalt and water etc. mixed and stirred, paved at normal temperatures
With roll, and then formed road surface structare layer a kind of waste and old RAP regenerative use technologies.Its advantage is mainly manifested in following side
Face：1. can realize that room temperature is constructed, it is not required to heated asphalt, the old again of fuel and waste asphalt mixture can be saved
Change；2. emulsified asphalt cold regeneration construction is convenient, using traditional asphalt construction equipment；3. emulsified asphalt is nontoxic,
It is odorless, nonflammable, and work progress is not required to heating raw materials, can effectively avoid the safety such as construction personnel's burn, bitumen poisoning
The generation of accident；4. the mixture proportion of waste and old RAP can reach 50~90%, the demand for reducing to new pitch and newly gathering materials, section
Energy consumption about in mineral aggregate recovery process, the cost that makes to build the road are greatly reduced, and economic results in society are notable.
One of the key link of emulsified asphalt cold recycling technology is the selection and application of efficient emulsified asphalt.In recent years, state
Interior road worker develops a variety of modified emulsifying asphalts, such as：The Lin Xixiong et al. of petrochina Co., Ltd, using pitch,
The components such as cationic emulsifier, copolymer emulsion develop a kind of emulsified asphalt, are mainly used for the surface abrasion layer of new pavement
And the maintenance of old pavement；Zhou Kai of Xuchang Goldroad Bitumen Co., Ltd. et al., using latex, polyolefin, poly- third
The components such as acrylamide, dextrin develop a kind of wide area high adhered modification emulsified asphalt, are used for bituminous coat project；Jiangsu dragon field synthesizes
The Hui Haihong of Materials Co., Ltd develops a kind of phenolic resin modified emulsification drip using materials such as phenolic resin, emulsified asphalts
Blueness is mainly used for friction material, refractory material and founding materials；The horse distance of travel of roc of petrochina chemical inc, height are virtuous and beautiful
Et al., using components such as SBS polymer modified emulsifying asphalt, mixed emulsifying stabilizer, acid, develops a kind of SBS polymer and change
Property emulsified asphalt, can be used for highway adhesion coating, sealing, slurry seal and top dressing etc..
Similar modified emulsifying asphalt material is a lot of, but compared with Emulsified Bitumen at Abroad material and technology, and China develops phase
To lag, main cause is the crack resistance at low-temperature and anti-fatigue performance after overtesting finds that emulsified asphalt mixes and stirs waste and old RAP
It is all poor, and after waste and old RAP has been added, power of regeneration is poor, directly affect reclaimed asphalt mixture stability,
Pavement performance and endurance quality.Cause the high-quality emulsified asphalt for efficient cold recycling technology less due to the above reasons, with state
The synthesis pavement performance of outer advanced emulsified bituminous materials differs greatly, and seriously hinders application and the hair of domestic cold recycling technology

(emulsified asphalt is formed contrast test group 2 by following raw material ratio：Graphene 3kg, used oil 13kg, devulcanized rubber powder 7kg,
70# matrix pitch 32kg, rubber and plastic stabilizer 3kg, emulsifier 8kg, water 34kg), and respectively by contrast test group 1 and contrast test
Emulsified asphalt in group 2 according to match ratio and waste and old RAP, miberal powder, newly gather materials, cement and water are sufficiently stirred, 2 groups are made under room temperature
Reclaimed asphalt mixture test specimen is spare.
Wherein, the basic mechanical performance of reclaimed asphalt mixture test specimen is verified by Marshall stability test,
The water stability and compatibility of reclaimed asphalt mixture test specimen are verified by indirect tensile test on frozen-thaw, is curved by girder low temperature
The crack resistance at low-temperature of reclaimed asphalt mixture test specimen is verified in song experiment, mixed to regeneration asphalt by fatigue loading experiment
The anti-fatigue performance for closing material test specimen is verified.
Test result is as shown in the table：
Known to being analyzed to above-mentioned test result：
1, by carrying out experiment comparison mixed with the test specimen of contrast test group 1 and nano modification emulsified asphalt C, although to having a competition
The volume of devulcanized rubber powder in group 1 is tested higher than the devulcanized rubber powder volume in nano modification emulsified asphalt C, but due to than experiment
It is not incorporated into graphene in group 1, the properties that test specimen is made are relatively low, it can thus be appreciated that whether graphene-doped for each of test specimen
Item performance has an impact.
2, the reclaimed asphalt mixture test specimen made of nano modification emulsified asphalt C and nano modification emulsified asphalt A systems
At reclaimed asphalt mixture test specimen compare, can prove graphene volume high energy improve test specimen anti-fatigue performance and compatibility
Property, but simultaneously as in nano modification emulsified asphalt C used oil volume be less than nano modification emulsified asphalt A volume, it is right
The crack resistance at low-temperature of test specimen, which is made, to be influenced.
3, test specimen made of the test specimen made of contrast test group 2 and nano modification emulsified asphalt A is compared, it is known that
SBR cations styrene-butadiene latex has an impact the properties of test specimen.
What has been described above is only a preferred embodiment of the present invention, it is noted that for those skilled in the art,
Without departing from the inventive concept of the premise, several modifications and improvements can also be made, these should also be considered as the guarantor of the present invention
Range is protected, these all do not interfere with the effect and patent practicability that the present invention is implemented.The present invention omits the technology of description, shape
Shape, construction part are known technology.
